None of the actual empirical economic data in the US resembles your statement - average household sizes have gone down over time, real incomes have gone up, and Gen Z wealth is doing fine.
It is true in the UK but that's simply because 1. the UK economy is doing pretty badly in general 2. you really, really don't build enough new housing.
If housing construction was unrestricted it wouldn't matter much what interest rates were at.
All of those articles are about economic performance before 2019, which was bad, but now we live in 2024, which is a different year where the economy is good. In fact it's as good as it's been in decades in the US. (Not so good in other countries partly because we caused inflation in their currencies.)
Note the media sector of the US economy is doing kind of badly and is mostly staffed by neurotic people who live in NYC, which means they tend to write negative articles no matter what.
